Abstract: Provided are methods and associated apparatus for determining the integrity of a hermetically sealed electronic component. The method and associated apparatus includes the use of an evacuation chamber configured to placing the hermetically sealed electronic component within. The evacuation chamber is then evacuated of atmosphere to then determine an atmospheric pressure evacuation relationship or curve occurring inside the chamber that is, in turn, used to determine the integrity of the hermetically sealed electronic component. Further aspects may include evacuating the chamber through a mass spectrometer coupled to the evacuation chamber for chemical analysis of at least one of the evacuated atmosphere for making further determinations of the integrity of the hermetically sealed electronic component.

Abstract: A system for measuring ionizing radiation with a scintillator incorporates a first assembly of at least two rod-shaped scintillator elements, which can be optically coupled to one another via their opposed face ends. The first assembly of scintillator elements is coaxially enclosed by a second assembly of interconnectable sheath elements. According to the invention, one scintillator element (11), one sheath element (12) and two face-end window elements (131, 132) form a scintillator module (10) in each case, which is optically and mechanically connectable to additional scintillator modules. The individual scintillator elements can thus be produced as encapsulated scintillator modules by means of “suitable” sheath elements and window elements. This provides for a simple and reliable manipulation and assembly of the measuring assembly at the site of its application.
